Abstract: A positioning device and a fastening device to fix the relative position of two or more adjacent tiles on a tiled display and to provide alignment. Fixing the relative position of two adjacent display tiles will facilitate the alignment of tiles in tiled displays where the seam between tiles will be as regular as possible, thereby avoiding the introduction of misalignments and their associated visual artefacts. The positioning device allows linkage of it to at least two tiles of a tiled display. The display tiles are often rectangular in shape and the positioning device is then located at a corner of the tile. The positioning device can also be attached to a support structure to make a tiled display.

Abstract: A method and system are described for adjusting displaying of images to be displayed on a display system. The method is suitable for display systems comprising at least one hardware feature (f1, f2, f3) influencing the display uniformity of the displaying of images, such as e.g. a defect pixel, seams, variations in positions of hardware components, etc. The method comprises obtaining pixelated image information to be displayed on a display system (100), and adjusting the displaying thereof by applying a distributed variation correction signal to the displaying of the pixelated image information. Such a distributed variation correction signal thereby takes into account the at least one hardware feature (f1, f2, f3) of said display system (100) so as to influence the perception of the display uniformity.
